It's not so silly. Netbooks account for a little over 20% of all PC sales now. The PC industry has not grown 20% over the same time period. Either netbooks are cannibalizing higher end/margin sales or they are masking what would have been a huge drop in PC sales over the last 2-3 years. I think one of the biggest problems with trying to makeup margins with higher volume is that support costs don't scale that well. It costs the OEM basically the same amount of money to offer telephone support and warranty service to a $400 machine as it does a $2k machine. So they make less money per machine and, because they sell more machines, it costs more to support them.
